Irregular period?

Meta

What would you guys do if you're still spotting after your last cycle? It has been more than a week since my cycle has ended and im still spotting. I typically have an irregular period but my cycle still only lasts for 4 to 7 days. I'm 20 years old and have had my period since I was 13. I thought it would have ended by now but each day that passes I get more and more freaked out..
